The valve is the character described, which is not only an imalso provided with a shoulder, boss or reducing u provement as aforesaid, but which is inexpensive portion 24, forming seating and positioning 'the bore I4.

means for a helical spiral spring 25 which seats at its other end on the shoulder 26 of the interior oi the housing. The valve head on portion 24 has a socket extension 21 having a spherical socket 28 opening inwardly, as clearly shown in Fig. 8. adapted to receive a ball 29 on or integrally formed with a reducing portion 30 of a rod 3|, which extends through a bore 32 in the threaded or notched connection extension 33, extending from or which is integral with the valve housing. The bore of the connection extension 33 is smaller in diameter than the diameter ol the valve chamber, as can be clearly seen in Fig. 1. Also, the rod is substantially smaller in diameter than the bore 32 of the con-4 nection extension 33.

The rod 3| has areduced portion 34 at or adjacent its inner or free end supporting a rounded or spherical swiveling knob 35 slidable thereon by means of a ilange 36. The connection extension 33 has an inner cylindrical face 31 forming the bore 32. A supply hose 38 is adapted to be pressed on to the extension 33, the hose having an inner cylindrical wall 39.

One of the principal objects of the ioregoin construction is to control the ilow of air in4 a simple, effective manner. To that end I provided means whereby air may be expelled from the nozzle of the device by merely bending the hose 39 sumciently to rock the valve of! its seat. This is accomplished because the inner wall oi the hose 39 will exerta pressure against the swiveling knob 35 on the rod 3|, which will iulcrum on the end of the inner cylindrical wall 31.- 'I'his will result in the movement of the universal ioint to rock the valve off its seat, as will be readily understood without detailed explanation. An illustration of the principle of the movement may be had from observation of Fig. 4.

It will be understood that normally the springv 25 and the air pressure tend to keep the valve seated upon its seat. It will thus be manifest that normally, when the device is held in one hand the power or supply will be shut oil. Thus, normally, there is no waste of supply and when it is desired to supply air, all that is necessary is to give a slight bend in the supply hose adjacent the swiveling knob.

In Figs. 4 and 5 I have shown a modified form. This form is largely similar to that shown in Figs. 1, 2, 3 and 8 excepting for certain changes which may be found desirable for use with water instead of air. In this form, the cap 40 is somewhat different from cap I3 having a ange 4Il the cap 40 being screwed into the threaded housing I2 the same way as did the cap I3.

The cap 40 has a nozzle extension 42 with an outwardly ilared inner bore 43 registering with The nozzle extension 42 is adapted to receive a protecting hose piece or outlet 44.

When my device is used for washing an automobile or the like where itis essential to prevent any scratches which might result from metal to metal contact, the protecting hose piece will permit close contact with the article to be washed and at the same time prevent any marking or injury of the same.

In the form shown in Fig. 4, the connection extension 33 has a larger diameter and is provided with an end wall 45 having a central aperture 46 andaplurality o! water ports 41. The rod 3| in the form shown in Fig. 4 extends through the central aperture 46 and is Provided with a xed knob 49.

In this form shown in Figs. 4 and 5. I have shown my invention adapted to supply water for the washing of a car, for example. In this case. the water will normally be shut oir. When it is desired to supply water, the valve housing may,

be grasped with one hand and bent relatively with the hose that is grasped by the other hand. When this is done, the inner wall of the hose will fulcrum the rod 3| in the central aperture 46.111 the end wall 45 -to rock the valve oi! its seat, permitting the water to travel through the ports of the end wall and around the notches of the bead and out through the nozzle opening as in Fig. 1. In they form shown in Fig. 4, it will be understood that the end wall 45 with its central aperture 46 serves as a fulcrum in the same way as the lower end of the inner wall of the extension 33 as at 31 in Fig. 1.

Because` of the larger diameters used in the form shown in Fig. 4, it will be found preferable to use the end wall construction shown.

In the two forms already described, the structures were designed primarily for use with ilex- V ible supplyhoses and in these cases. either the hose or the valve housing could lbe grasped an the hose bent to open the valve.

In the last form which I have shown in Figs. 6 and 7, the valve construction is adapted to be used most advantageously with a fixed non-nexing source of supply,` as will be readily apparent hereafter. In the form., shown in Figs. 6 and '1, the cap 49 is similar to the cap I3 excepting that it is provided with a tube 55, it being understood that this form of construction is also adapted for the use of water.

In the packing ci' sausages and such. one of the usual operations is a test operation to learn if the casing for the sausage is satisfactory before packing the sausage meat into the casing. The form oi my construction shown in Figs. 6 and 'l is particularly adapted for this function inasmuch as the tube 59 may be inserted into the casing and water injected into the casing to expand the casing to the necessary size to make sure thatthe casing is leak-proof or otherwise suitable.

In the form shown in Figs. 6 and '1, there are also provided a housing valve and seat and joint and other details similar to those shown in Fig. l. A coupling hose 5I, which may be provided with the usual clamping rings, is pressed on the connecting extension 33 and to another connecting extension 52 of a coupling member 53.

The coupling member 53 has a reduced bore 54V (and a large threaded bore 55, as is clearly shown in Fig. 6. A fulcrum ring 56 is threaded into the large threaded bore 55, the ring having a central aperture 51 and a plurality of ports 58 for water. The coupling 53 may be threaded onto a supply pipe 59 which may be stationary or ilxed and nonflexing.

It will be understood from Fig. 6 that the rod 3Ia, which is much like the rod 3I of Fig. l, extends through the bore 32 in the connecting extension 33 and then through theV bore 54 in the coupling extension 52 all within the coupling hose 5| and thence through the central aperture 51 in the ring 56 and thence into the interior of the stationary pipe 59.

It will be observed from Fig. 6 that there is a space between the end of the extension 52 and the adjacent end of the extension 33, and when the construction shown in Fig. 6 is mounted in place on the stationary supply pipe 59, the water amasar it is desirable to stop the supply of water, all' that is necessary is to release the hand and allow the structure to return to its natural position.

While I have illustrated and described the preferred form of construction for carrying my invention into eiIect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
